Achieving excellent vehicle dynamics and exhaust efficiency by reducing weight and back pressure
  • Honda Civic 2017-2021 Hatch (Sport Models Only)
  • Redesigned: The SPEC L II muffler has been redesigned to match the bumper shape of the 2020 Honda CIVIC Hatchback. It can be installed on 2017-2019 models as well. The existing 31019-AH107 will be discontinued. Please refer to page 2 for details.
  • 30% weight savings: HKS uses thin stainless-steel material for the pipe and silencer to achieve weight reduction compared to the stock muffler. Stock: 17.5kg, SPECL II: 12.3kg
  • Elaborated sound quality and low back pressure: It provides a sporty bass sound during the acceleration and eliminates uncomfortable drone sound at the normal rpm range. In addition, the straight structure silencer achieves about 40% less low back pressure compared to the stock.
  • The shape of the rear bumper varies by vehicle/country.
  • The new 31019-AH108 can be installed on either bumper shape.
  • The existing 31019-AH107 will be discontinued.
